HAND ADDRESSING-MACHINE.

Specification of Letters Patent.

Application filed'November 19, 1914. Serial No. 872,922.

class of machines now generally referred to l as addressmg machines, but which are adapted for and are often actually used not only to print addresses but other information of great variety.

The primary object of the invention is to provide a machine of this type for those who only require such a'machine for brief periods and at more or less infrequentintervals, to print shipping tags, for example, and whose requirements will be satisfied by a hand operated machine of simple construction,

In a machine intended for the purposes noted it is desirable that the printing device should be readily inserti'ble inprinting position and as readily removable therefrom to allow the insertion of a fresh printing device, so that the work can be performed by unskilled operators. It is frequently desirable to make a plurality of impressions from the same printing device and for this reason my present invention provides that the printing device will remain in printing position until released by the operator and then will be automatically moved from printing position to a point where it may be readily grasped by the operator and removed from the machine with one hand while the'operator inserts a fresh printing device with the other hand.

My invention also has for its object to provide a machine of simple and inexpensive construction, consistin of few parts, which can beeasily operated by hand at a relatively high speed in the manner and for the purposes indicated and as more fully pointed out hereinafter. a e

Other objects and advantages of my invention will be apparent as the same is better understood by reference to the following description when considered in connection with the accompanying drawings in which- Figure 1 is a plan view of the invention with the impression arm and platen broken away;

Fig. 2 is a. Vertical section on the line 2-2 of Fig. 1;

Fig. 3 is a vertical section on the line 33 of Fig. 2 with a portion of the mechanism removed; I i

Fig. e is a detail of the locking and ejecting mechanism for the printing plate;

Fig. 5 is a detail perspective view of the releasing lever; and

Fig, 6 is a detail perspective view of the printing plate locking plate;

Referring to the drawings, 1 designates the machine base which is provided with a recess 2 extending outwardly from printing position and preferably through the front edge of the base. This base may be made in any suitable form to accommodate the mechanism and it is provided with an impression bed 8 in printing position and with tracks 9 extending from the bed 8 outwardly atthe sides of the recess to support and guide the printing device while the latter is being arranged in printing position on the bed and also whlle being e ected therefrom. Grooves 9f are provided in the base of the-machine at the outer edges of the tracks 9 to accommodate the spacing flanges commonly provided on printing devices used in this class of machines and as the arrangement of the grooves and guide tracks is preferably made tocorrespond to the size of the printing device and the arrangement of the spacin flanges thereon it will readily be perceive that the grooves and tracks also serve to guide the printing device in its movement to and from printing position on the bed. A

platen 3 is carried in operative relation to the printing bed on an arm 4: which is pivotally mounted at 4 on the base. A spring 5 connected at 6 to the base and at 7 to the arm normally holds the platen or impression arm in raised position. An inking ribbon 10 is mounted on'spoolsll h'aving ratchet teeth 12 and disposed through the machine as shown in Fig. 3, these spools being rotated through a connection with the platen arm or in any other suitable manner.

Means are provided for retaining the plate in fixed position on the bed during the printing operation and when it is desired to remove the plate the said retaining means are released, whereupon ejectin means automatically operate to eject t e plate from printing positi011,beneath the ribbon, on to the tracks in convenient position for removal manually from the machine.

The retaining means comprises a plate 15 fastened to the base at 15 and provided with looking dogs 17 disposed in the grooves 9 in front of the printing bed to engage the forward edge of the'printing device after the latter has been arranged in printing position on the bed. The upper edges of these locking dogs are inclined upwardly and rearwardly and the extreme rearward ends17 project up in the path of move ment of the plate along the tracks. This locking plate is guided on a bolt 1% which is slidably arranged in a lug 13 on the base and is provided with a spring 14 between the plate and the lug. This spring normally sustains the plate in elevated position with the rear ends 17 of the dogs arranged to engage the front edge of the plate, it being readily understood that the dogs will yield as the plate is slid thereov'er along the tracks into printing position on the bed and then return to elevated position in front of the plate. A finger piece 16 is loosely mounted on the bolt 14 above the plate 15 and is pro- 1 vided with a shoulder 16 which engages and depresses the plate 15 when the finger piece 16 is depressed. Thus, by depressing the finger piece the locking plate is also depressed to carry the dogs out of the path of the printing. device.

The ejector comprises a pair of upwardly projecting arms 18 pivotally mounted at 19 on the rod 20 secured in the frame. A cross bar 21 connects the arms 18 and a lug 22 thereon engages a washer 23 which is located' at one end of the expansion spring 25 on the bolt 2% secured to the base.

In practice the operator inserts a printing device 26 (Fig. 4) on the tracks 9 and moves it along the tracks into printing position beneath the ribbon 10 and upon the bed 8. The ejector arms 18 are forced to the position indicated by the dotted lines on Fig. 4;, against the action of the spring 25, when the printing plate is moved into printing position on the bed, by engagement of the print ing device with said arms. Ihe clogs-17 on the locking plate 15 retain the printing device in printing position and the ejector arms, push the device against said dogs. The impression arm 1 may now be operated to obtain the desired number of impressions. To remove the printing device the operator depresses the finger piece 16 which in turn depresses the locking plate 15 and the dogs 17 to. release the printing device and the spring 25 forces the ejector arms 18 forwardly, thereby ejecting the printing device from printing position on the bed beneath the ribbon to a position on the tracks 9 where it may be readily grasped and removed. It will be found convenient to re move the printing device from the machine with the left hand while inserting another printing device with the right hand.

It will be understood from the foregoing description that I have devised a simple form of hand addressing machine which is adapted to be operated at a high rate of speed and with great ease, because of the rapidity with which the printing plates may be inserted and removed from the machine during the operation. After a printing de vice has been inserted in the machine any number of impressions may be taken without loss of time and without movements other than those necessary in inserting the material to be printed and in operating the impression lever.

It will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing any of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.

I claim:
